Switch (case) in JavaScript

---

examples/js/switch.js

"use strict";

var n = 42;

switch (n) {
  case 1: {
    console.log(1);
    break;
  };
  case 42: {
    console.log(42);
  };
  case 'other': {
    console.log('other');
  };
  default: {
    console.log('default')
  };

}

// 42
// other
// default

• You'd better call "break" at the end of each "case" statement or this will fall through and will execute all the lower cases without checking their condition.
• Switch uses === for comparision.
• We can put variables instead of the fixed values in the 'case' statements.
• If the same value appears in more than one 'case', only the first one will match.
